While estimating project costs, a project manager works with a subject matter expert (SME) who has historically underestimated the effort necessary to deliver project requirements. In all other areas, however, the SME is a good contributor, well respected, and often requested by stakeholders. To proactively mitigate the risk of underestimation, what should the project manager do?
A. Periodically review objectives and requirements with the SME during estimation and use other resources to review the submitted estimates
B. Ignore previous issues with estimates from this SME and continue with the process unchanged
C. Notify project stakeholders that any estimates submitted by the SME must be increased by 20 percent
D. Remove the SME from the project and request a resource who can provide more accurate estimates
